If so, what type? - saline - sodic - not salt affected - saline-sodicQ-12. Complete the table:- Things directly related to Soil Things indirectly related to Soil
- Write T on the blank provided if the statement is correct. If it is false, underline and replace the word(s) with the word(s) that will make the statement true. Calcium carbonate is highly soluble in water in which calcium element is easily release to correct soil pH. The degree of fineness of lime is not dependent to the speed of checking soil acidity. Carbon is released back to the atmosphere during decomposition of organic materials. Mineralization of nitrogen decreases if the water filled pore space is below 50%. Soil carbon mineralization increases as the moisture content of the soil increases to a certain level and may drop if soil is fully saturated with water. Nitrifying bacteria that obtain carbon from carbon dioxide prefer reduced zone to nitrify nitrogen to available form.Figure 31.6 Soil compaction can result when soil is compressed by heavy machinery or even foot traffic. How might this compaction change the soil composition?Cation Exchange capacity is: Group of answer choices a. The amount of cations that can be held by a given mass of soil. b. Affected by soil texture c. Affected by the amount of organic matter/Humus in a soil. d. Affected by the amount of clay in a given soil e) All of the above

O True O False ntoin onvironmental 2 poinObservation: I want to know what effect salt has on the growth of grass. So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?Soils & Erosion 1.Describe the relationship between soil particle size and important soil characteristics (i.e., drainage andaeration). 2.What soil horizons contain the most nutrients? Why? 3.Describe the various kinds of living organisms that make up the soil community & how they interacttogether. Briefly indicate the role(s) ofeach.
- of this practice with respect to plant nutrition?3. WHAT IF? How would adding clay to loamy soil affectcapacity to exchange cations and retain water? Explain.Would the particle density of a soil high in organic matter be the same? Higher or Lower? Why?Soil characterisation could help to determine soil type and soil health. Relate cation exchange capacity (CEC) with soil health and explain the roles of clay and organic matter in contributing to CEC. (i) What would you recommend to improve soils with low CEC and high CEC? Name ONE (1) negative effect of low CEC and high CEC soils, respectively. (ii) (ii) Suggest a suitable soil type for rice, oil palm and durian, respectively.
